Key points:

the paper was obviously fake to a human reader: it starts by saying it's fake and says it multiple times throughout

the paper says it was funded by the Professor Sideshow Bob University of Trickery and thanks contributors from the USS Enterprise and the Fellowship of the Ring

the paper has already been erroneously cited in a real research paper

LLMs give different information depending on the prompt, so sometimes they mention that the fake condition is "perhaps pseudoscience" and sometimes they tell people to see a doctor because they have the fake condition

absolutely no one is taking any responsibility for this shit, except maybe Nature, because they retracted the paper that cited the fake paper
